I recently repainted mine after stripping them myself. The painting part is easy, it is the stripping part which is a pain in the ass. I purchased Argent Silver wheel paint from Eastwood and topcoated it with some of their diamond clear top coat. Of course like most of my projects, a month or two after I finished IPD starts selling products that I couldn't find earlier. If I were you I would go with with the IPD paint, as I am not really happy with how shiny mine ended up looking. They look nice but they don't have the satin look of the stock paint.

Or you can go ahead and do the mercedes look and paint the rims the same as your car color. That is how the paint is on my 210, the paint matches the primary color of the car. You could even paint behind the V on the hubcap to match
